Fires right up and I can get on it and go and get it up to 28 to 30 mph. But soon after that with the throttle wide open starts to decelerate and the power goes in and out and I can't get it over 22 mph. When it starts decelerating if I let off the gas and then give it gas again it starts to go. But Then it start to decelerate after a minute or so. Any ideas?
Thanks for any help, Marty
